HAND-OPERATED BRICKMAKING MACHINE.

Application filed July 24,

T 0 all whom it may concern:

Be it known that CHARLES Covr, a citizen of Italy, residing at Riverton, in the county of Crow Wing and State of Minnesota, has invented certain new and useful Improvements in Hand-Operated Brick making Machines, of which the following 1s a specification.

In carrying out the present invention it is my purpose to provide a brick making machine wherein the same is operated manually, the nature of the same being such as -to allow a great number of bricks to be manufactured in a relatively short period of time.

The primary object of the invention is to provide such a hand operated brick making machine that is, comparatively speaking, simple of construction, cheap of manufacture and easy and simple of operation, the device comprising, relatively speaking, substantially few structural elements and these co-related in such a manner as to reduce the possibility of disarrangement to a minimum.

A further object of my invention resides in the provision of such a hand operated brick making machine that includes a reversible mould, i. e., a mould that is provided with brick compartments in its upper and lower sides whereby said mould may be rotated within its support for permitting the bricks in the under side to be discharged therefrom while the compartments in the top side are being filled.

A still further object of the invention is to provide such a machine wherein this reversible mould includes a novel brick discharging mechanism.

IVith the above and other objects in view as the nature of the invention is better understood, the same comprises the novel construction, combination and arrangement of parts set forth in the following specification and shown in the accompanying drawings.

In the drawings wherein like reference characters indicate corresponding parts throughout the several views;

Figure 1 is an elevation of one side of my improved machine,

Figure 2 is a front elevation thereof,

machine for more clearly disclosing the reversible brick mould element per se, Figure 5 is a top plan view of the mould,

Figure 6 is a vertical longitudinal cross section thereof,

Figure 7 is a detailed cross section taken substantially upon the broken line 7-7 of Figure 6, and

Figure 8 is a perspective .of the raising mechanism per Se, for the material hopper.

Now having particular reference to the drawings, my novel hand operated brick making machine comprises essentially a pair of relatively wide end standards 5 the lower ends of which are bifurcated toprovide supporting legs 6 as more clearly shown in Figure 1, the upper ends of these standards being formed at their rear edges with vertical posts 7. Fixed to the inner side of each of said standards 5 and extending rearwardly and upwardly therefrom is an arm 8, to the free end of each of which is fixed the lower end of an upwardly extending link rod 9, the opposite end of each of these link rods being pivotally secured at 10 to the under side of the material hopper 11 and at a point adjacent its rearmost end. Extending transversely beneath this material hopper 11 adjacent its outlet end is a rock shaft 12, more clearly shown in Figure 8, to the opposite ends of which are fixed downwardly and forwardly extending arms 13. Fixed to the front .ends of these arms 13 are upwardly extending arms 14; that are pivoted at 15 to the posts 7,.the extreme ends of these arms 14: be ing slightly curved rearwardly and adapt ed for contact with inwardly directed pins 16 carried by said posts 7 for limiting the swinging movement of said arms 14 in a certain direction. Formed upon the lower is a relatively J-shaped operating lever 17 Pivoted to the front end of each of the arms 13 that are carried by the opposite ends of said rock shaft 12, is a rearwardly extending link rod 18 that is pivotally secured at its opposite end to said material hopper 11- at the point of pivotal connection between this material hopper and each of said link rods 9, above described. 7

It will, of course, be understood from the foregoing description that when the material hopper 11 is positioned as shown in Figures 1 and 2, the. material therein may be raked into the mould designated generally A and, after a sufficient amount of material has been discharged into this mould it is necessary that the material hopper 11 be raised upwardly for permitting the tampers designated generally -13 to be properly actuated and this operation may be accomplishel by pulling downwardly upon said lever 17 which moves the rock shaft 12 beneath the forward end of said material hopper for consequently swinging the same upon an are for thereby removing the diseharge'end thereof from-a position directly between said mould A and the tamping element B.

The said mould A carries at its opposite ends projecting pintles 19 that are j ournaled within bearings 20 upon the upper ends of the standards 5, the pintle on the right hand end of the mould carrying a collar 21 that is formed upon opposite sides with lugs Pivoted to the adjacent post 7 at one end is a hand lever 23 that is provided intermediate its end with a notch 2 L that is adapted for engagement over a selective one of said lugs carried by the collar 21 for holding the mould "A against rotation.

Referring particularly to Figures 5, 6 and 7, the said mould A embodies a substan tially rectangular shaped casing 25 the upper and lower sides of which are open. This mould is formed at its upper and lower sides with longitudinal and transverse partition walls 26 for dividing the same into brick compartments 27 at its upper and lower sides. The compartments within the opposite sides of this mould are in alinement with each other and movable within said compartments are brick discharging plungers 28 each of which is formed with an inwardly extending arm 29, the arms of the plungers within alined compartments being pivotally joined together at 30 while extending longitudii'ially through said mould and secured to the ends of the arms 29 of the plungers within alined compartments are bars 31, the opposite ends thereof extending through vertical slots 32 within the end walls of the mould. casing and being headed at 33.

Extending transversely through the mould beneath the compartments 27 at the upper and lower sides thereof are rods 34 that serve as a means for limiting the downward movement of the plungers 28 within the compartments 27 in a manner clearly shown in Figure 6.

In actual practice, when the elements are positioned as shown in Figure 1 and the plungers 28 within the compartments 27 at the top side of the mould are arranged as shown in Figure 6, the material may be raked from the hopper 11 into these moulds. After the material has been poured into the mould compartments the material hopper 11 is raised as before described and after this operation has been completed a hand lever 35 that is pivoted at 36 between the upper ends of the before mentioned posts 7 is pulled downwardly, which hand lever is operatively connected to tamping blocks 37 carried by a cross board 38 whereby the material. within the hopper compartments may be thoroughly tamped. tion between the hand lever 35 and said cross board 38 that carries the tamping blocks 37 includes connecting links 39 that carry L-shaped brackets 40 extending outwardly therefrom and provided with openings for the reception of guide rods i1 Figure 1 whereby said tamping elements are guided in a vertical movement. The rear end of said hand lever 35 extends beyond the posts 7 and between said rear end of the hand lever and said posts are springs 42 that serve as a means for main taining said hand lever in the position of Figure 1 and consequently raising the tamping blocks 37 away from the compartments within the mould A- After the compartments within the top side of the mould A have been filled and the material therein properly tamped, a cover plate 43 is positioned thereon, the same being maintained in position upon said mould by pairs of latch elements 44 at opposite ends of the mould. The upper and lower sides of this mould are sin'lilarly equipped with said latch elements 4% and the alined latch elements upon the opposite ends of said mould are inter-connected by inwardly extending links 45 that are pivoted. at one end to the lower ends of said latch elements 44, the inner ends of these links being pivoted to the opposite ends of link plates 46. These link plates are fixed to the opposite ends of certain of the before mentioned rods 34 that extend transversely through said moulds, these particular rods being journaled through openings in the side walls of said moulds whereby rotation thereof will consequently cause a movement of the link plates 46 at opposite sides of the mould for consequently moving the latch elements 44 to locked or unlocked position. Each of said link plates 46 is formed at its lower end with an outwardly extending knob 47 whereby the same may be actuated.

After the cover plate 43 has been positioned as above described the before mentioned lever 23 is raised for consequently allowing the mould to be rotated to the position shown in Figure 4. After this mould has been moved to the position shown in said figure, the hand lever 35 is actuated and arms 48 formed, upon the lower ends of the connecting rods 39 between the cross board 38 that carries the tamping element The connecill) 37 and the said hand lever will en age the headed ends 33 of the longitudinal are 31 movable within said mould A for thereby actuating the plungers 28 and consequently forcing the bricks out of the compartments within the lower side of said mould. It is of course to be understood that preliminary to this operation the latch element @4: upon the underside of said mould be released.

Beneath the mould -A and slidable within guides 49 upon the inner side of said standards 5 is a depressible roller platform 50 which carries, adjacent its opposite ends, pendent rods 51 movable through openings in a cross board 52 between said standards 5. Encircling these rods 51 are coil springs 53 that serve as a means for normally main taining said roller platform 50 in the position as shown in Figure 2. ()peratively connected to this platform 50 is a foot lever 53 whereby when the bricks have been discharged from the mould A on to the platform the same may be depressed, for alining with a roller platform 54, extending sidewise from one of the standards 5, thereby permitting the bricks to be shoved thereon, after which they may be carried to the kiln.

In view of the above description when considered with the accompanying drawings, numerous advantages of a hand brick making machine of this character as well as the operation thereof will be at once apparent to those skilled in the art and even though I have herein set forth that this invention constitutes certain detail structural.

elements, it is nevertheless to be understood that I do not wish to limit myself to such a showing as in the future practice of the invention modifications may be had therein without departing from the spirit and scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a brick making machine of the character described, a supporting frame, a reversible brick mould rotatably mounted upon said frame and being formed with brick compartments in its upper and lower sides, a material hopper supported upon said frame whereby the compartments of said brick mould may be filled, manually controlled means for tamping the material within the compartments of the mold, means for discharging the bricks from the mould, said means comprising plungers movable within said mould and hand operated means for actuating said plungers.

2. In a brick making machine of the character described, a supporting frame, a reversible brick mould rotatably mounted upon said frame and being formed with brick compartments in its upper and lower sides, a material hopper supported upon said frame, whereby the compartments in said brick mould may be filled, manually controlled means for tamping the material within the compartments of the mould, means for discharging the bricks from the mould, said means comprising plungers movable within said moulds and hand operated means for actuating said plungers, and a roller platform supported beneath said mould, adapted to receive the discharged bricks from the mould.

3. In a brick making machine of the character described, a supporting frame, a reversible brick mould rotatably mounted upon said frame and being formed with brick compartments in its upper and lower sides, a material hopper supported upon said frame, whereby the compartments in said brick mould may be filled, manually controlled means for tamping the material within the compartments of the hopper, means for discharging the bricks from the mould, said means comprising plungers movable within said mould and hand operated means for actuating said plungers, a roller platform supported beneath said mould, adapted to receive the discharged bricks from the mould, said roller platform being depressible and a stationary platform upon one side of said supporting frame whereby the bricks upon said first mentioned platform may be brought to a position to be moved thereon.

In testimony whereof I ah'ix my si iature.
